Vacuum accessories
Vacuum technology
Festo's vacuum accessories programme includes vacuum filters of the ESF series and an extensive range of suction cup holders from the ESH line. The vacuum filters ESF-3 and ESF-4A/4B protect ejectors and downstream control components from particle ingress on the suction side. Suction cup holders of types ESH-HA, ESH-HB, and ESH-HC allow connection of bellows cups via PK and QS push-in fittings or G-thread ports in sizes 1 to 6.
Selection of the correct suction cup holder depends on the port type of the bellows cup being used and the bore diameter of the air line. ESH-HA variants offer straight connections, ESH-HB provides angle versions, and ESH-HC covers further geometries. Vacuum filters should be installed between the vacuum source and ejector whenever dusty or particle-laden workpieces are handled.
Typical applications: Extension and maintenance of existing Festo vacuum systems in assembly automation, retrofitting filter components to vacuum nozzles in dusty production environments, and system-compatible expansion of vacuum handling units in the electronics and packaging industries.
